Filed: 1928-01-19
Abstract: 283,935. Siemens & Halske Akt.- Ges. Jan. 20, 1927, [Convention date ]. Selective distant control systems; tell-tale apparatus.-In an electric distant control system wherein each unit to be controlled has a manuallyoperated control member and a manuallyoperated position indicator and wherein an alarm is given when the positions of the unit and its position indicator are not in agreement, the control member and the associated position indicator are arranged concentrically in order to save space on the control panel. As shown in Fig. 1, the apparatus unit 1, which is operated by a switch 24, controls an auxiliary switch 8 which together with a hand-operated switch 11 at the control station controls a relay 10. When the switches occupy corresponding positions, the relay 10 remains de-energized and a lamp 15 is steadily illuminated from the supply 4, 5. When, how. ever, the unit 1 changes position, the relay 10 connects the lamp in series with an interrupter 17 which produces flashing. The switch 11 is then operated to establish steady conditions. The switch 11 may be coupled mechanically to a switch 18 which controls signalling apparatus. Figs. 2 and 3 show a constructional arrangement of the control and supervisory apparatus at a control station for a single substation unit. The control switch 34 is mounted on a sleeve 33 having an operating flange 32 projecting in front of the control station panel 31. The sleeve 33 is rotatably mounted on a cylindrical member 37 which forms a bearing for a hollow member 39 carrying the switches 11, 18. The member 39 houses a lamp 314, which may be used for indicating disagreement between the switch 11 and the apparatus unit, and is operated by a projecting and transparent front 316, the position of which indicates the position of the switch 11 and consequently the position of the associated substation unit when the lamp is steadily illuminated. In a modified arrangement, the interrupter 17 is replaced by a condenser and resistance, Fig. 4 (not shown) arranged so as to produce an intermittent discharge of a lamp.

Title: A machine for the delivery of articles, more particularly bulb-shaped or tuberiform agricultural and horticultural produce
IPC: B65G47/29
Filed: 1951-01-26
Abstract: 685,018. Counting-apparatus. VRIES, S. DE. Jan. 26, 1951 [Feb. 2, 1950], No. 2072/51. Class 106 (i). Apparatus for the delivery in succession of equal multiples of articles, such as bulb-shaped or tuberiform agricultural and horticultural produce, supplied to inclined shoots 1, each terminating with a hinged closure member 3, is provided with control means for each closure member comprising an air cylinder 16 containing a piston 17 and communicating with a pressure chamber 14 enclosing a diaphragm 12 secured to one open end of an axially movable tube 11 on the other end of which is fixed a transverse tube 9 carrying normally open nozzles 8, each regulated by a spring-controlled valve bearing on the corresponding closure member. In the apparatus shown, articles are placed in a series of inclined tubular receivers so as to press down associated pivoted flaps 3 and to cause spring-urged valve heads 7 to close the nozzles 8. When the piston 17 is moved down, air is forced through chamber 14, tubes 11, 9 and nozzles 8, the valve heads 7 then being forced upwards. When the piston is returned, if all the receivers 1 are filled, the heads 7 will cut off communication with the atmosphere, and the suction will pull down diaphragm 12 and the tube and nozzle assembly against a spring 21, thus allowing the flaps 3 to move to the position shown in broken lines, and the articles resting thereon to drop out. At the same time, the air pressure above the piston, supplied via conduits 23 to rubber linings 22, will hold the remaining objects in the receivers 1. When the tube 11 reaches the lowermost position atmospheric air is supplied via channels 25, 24 as well as via the released valve heads, thus returning the diaphragm and tube and nozzle assembly to the normal position shown. A counting device (not shown) may be associated with the tube and nozzle assembly to count the number of strokes thereof. The flaps 3 may be right-angled levers which operate horizontally moving valve heads 7. A modified form of valve also is described.

Title: The manufacture and application of new textile assistants
Filed: 1934-01-22
Abstract: Urea is condensed with two or more (up to about 55) molecular proportions of ethylene oxide, and the products are acylated with an acid derived from a natural fat or fatty oil.  The urea-ethylene oxide reaction may be promoted by a catalyst, which may be a substance having an alkaline reaction in aqueous solution, e.g. sodium hydroxide, sodium carbonate or borax, or a surface active material, e.g. silica gel, diatomaceous earth, or a natural or synthetic zeolite.  The acylation reaction may be effected with the free acids or their anhydrides or halides.  The products are useful as textile assistants, particularly as wetting and emulsifying agents.  In the examples, (1) urea is heated with 30 times its weight of ethylene oxide, and the product is heated with stearic acid; the acylated product so obtained may be added to an indigo vat, whereby slightly greener dyeings, much faster to rubbing, are obtained; the product may also be added to the baths used in dyeing with chrome blacks, whereby dyeings fast to rubbing are obtained; (2) urea is heated with 35 times its weight of ethylene oxide in the presence of caustic soda, and the product is heated with oleic acid; (3) as in example 2, except that ricinoleic acid is used instead of oleic acid; the product may be used as an emulsifying agent for mineral oils; (4) as in example 2, except that slightly less ethylene oxide is used, and the product is acylated with lauric acid.  Palmitic acid or its anhydride or halides may also be used as acylating agents.  The Provisional Specification states that the unacylated urea-ethylene oxide reaction products may be used as wetting and emulsifying agents.ALSO:Products useful as emulsifying-agents are obtained by condensing urea with two or more (up to about 55) molecular proportions of ethylene oxide, and acylating the products with an acid derived from a natural fat or fatty oil.
